3 Claims.

This invention relates to spring foundations. It is particularly directed to a spring seat for upholstered furniture.

In spring seats having coil springs, the springs have hitherto been tied to each other and to the frame with tie-cords. These tie-cords very often tear and are difficult to attach in place. It is therefore an object of this invention to provide a spring seat for upholstered furniture having improved means for attaching the coil springs on the webbing to each other and to the frame.

Another object `of this invention is to provide a spring seat of the character described having ribbons or strips of textile material over the tops of the coil springs, said strips being attached to the top convolutions `of the coil springs by rings or clips and the ends of these strips being at tached to the walls of the seat frame.

Another object of this invention is to provide a spring seat of the character described having improved means for pulling down the attaching strips at the front end of the frame for tensioning said strips.

Yet another object of this invention is to provide a highly improved spring seat construction of the character described which may be applied to either hard edge or soft edge seats, and which shall be relatively inexpensive to manufacture, easy to apply, and yet practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application Will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention.

Referring now in detail to the drawing, IIJ designates a spring seat construction for upholstered furniture embodying the invention. The same comprises a frame II having a front wall I2, a rear wall I3, and side walls I4. The frame may be supported on front legs I5 and rear legs I5. Attached to the underside of the frame is a webbing I'I. The webbing I1 may be a piece of burlap attached at its edges to the underedges of the frame. On the webbing I'I are a plurality of rows of coil springs I9.

Improved means is provided for attaching the coil springs to each other and to the frame. To this end there is provided a plurality of transverse strips 22 made of textile material. Strips 22 may be of canvas, burlap, twill, or any other sto-ut textile material. Each strip 22 passes over the top of a row of springs I9. The ends of strips 22 are attached to the upper edges of side walls M, as by nails 23 or the like attaching means. Each strip 22 is attached to a top convolution 26 of a coil spring I9 by means of hog rings or clips 2l which pass around the top convolution and through the strip. Preferably each strip is attached to one spring by a pair of rings 21 1ocated at diametrically opposite sides of the top convolution of the spring, and at opposite edges of the strip.

There is furthermore provided a plurality of strips 3l! extending from front to rear, onev for each. row of springs. The rear ends of the strips 3B are attached to the upper edge of the frame by nails or other fastening devices 33. Strips 30 Dass over the tops of the coil springs i9 and over the strips 22, across the latter. Strips 30 are attached to the top convolutions of springs I9 also by means of diametrically opposed hog rings or clips 38. Each strip 30 is attached to one of the springs by a pair of clips 38 passing around the top convolution of the spring and through op` posite edges of the strip. The front end of strips 3l] are attached to the upper edge of front wall I2 by nails or any other fastening means 40.

Means is provided for tensioning the strips `3l) adjacent the front wall I2. To this end there is attached to the inner surface I2a of front wall I2, a horizontal strip 59 likewise made of textile material. The strip 50 passes over each of the strips 39 and is attached to the wall I2 by nails or other fastening devices 5I at opposite sides of each strip 39. The strip 38 is thus looped and pulled downwardly as at 52 in front of wall I2 so as to tension strip 38.

The strips 22 and 3U being at and wide, make a good bearing surface for padding placed over the springs. The strips 39 are preferably about one inch in Width. They could be between onehalf inch and one and one-half inches, if desired.

The spring construction shown in Figs. 1 and 2 is a hard edge spring construction. In Figs, 6, 7 and 8 is shown a soft edge spring construction embodying the invention. In Figs. 6, 7 and 8 there is shown a spring seat 6U comprising a frame 6I having a front wall 62, a rear wall 63, and side walls 64. The frame may be supported on front legs 65 and rear legs 86. Attached to the underside ofthe frame is a webbing 6l. On the webbing (il and within the frame are a plurality of rows of coil springs 89. The front row o f springs 69 rare close to the iront wall 82. The front row of springs are also interconnected by an vvedge wire 19, attached to the frame as by brackets II and clipped to the upper convolutions of the iront row of springs as by metal clips '|2.

The rows of springs are attached together and tothe frame by means of a plurality of strips I5 extending from front to rear. The rear ends of the strips l5 are attached as by nails 'I6 to the upper edge of rear wall 63. Strips l5 pass over the tops of the rear springs of each row and over the rear edge of the top convolutions o f the front spring of said row. rIhe strip I5 has a portion l1 passing down through the spring and then looped upwardly about strip 85 and extending at "i8 over the top edge of front wall 82. Extending from portion 'i8 is a strip portion 7,9 which again passes upwardly and rearwardly through the spring and over the top of strip l5. Strip portions i8 are attached to the front wall by nails or other attaching means 38. The outer end of strip portion 'i9 is attached to strip 7,5 by hog rings 8l which pass around the rear sides of the top convolutions of the springs G9 at the front of the frame. Strip 'I5 is attached to the rear springs in each row by hog rings 83. The hog rings 83 are disposed at opposite sides o f strip l5 and at diametrically opposed sides of the upper convoiutions oi the springs.

vMeans is provided to tension the strips I5 adjacent their front ends. To this end there is attached to the inner surface 62a of front wall 62 of the frame a horizontal transverse strip or ribbon 8,5 of textile material. Strip 85 has looped portions 86 looped over the loop portions 'I'I of the vstrips l5. Strip 85 is attached to the front wall by nails or attaching means 8l at opposite sides of the loops 86. VStrip 'I5 is thus tensioned downwardly.

Means is provided to tie down the front portions of the upper convolutions of the springs 6.9 in the front row. To vthis end there is provided, for each of the front springs, a strip 98 having one end 9I lattached to the upper edge of 4`the iront .wall 62 by ,the attaching means 88.

Strip passes over the edge wire 'I0 and over the top of the iront spring 69 and is attached to the strip portions 'I'I and 'i5 by said hog rings 8|.

Transverse strips are also provided for each transverse row of springs. Said strips 95 have the ends thereof attached to the side walls 64 of the frame by attaching means 96. The strips 95 overlie the rows of springs 69 and cross the strips l5 and are attached to the top convolutions of the springs by hog rings 9T. The strips 95 are attached to each spring by a pair of hog rings 97 located at opposite edges of `the strip and at diametrically opposed 'portions of the spring.

it will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
